3.1 About the WP-230
The Kramer WP-230 XGA/Video/Audio Line Driver wall plate includes:
 A computer graphics XGA INPUT on a standard HD-15 connector
 An amplified and equalized RGBHV output on 5 BNC connectors
 A composite video input on an RCA connector with a corresponding
composite video output on a 2-pole terminal block
 An s-Video input on a 4p connector with a corresponding s-Video output
on a 4-pole terminal block
 An unbalanced stereo PC AUDIO INPUT on a 3.5mm mini jack with a
corresponding balanced stereo PC AUDIO OUT on a 5-pole terminal block
 An unbalanced stereo LINE AUDIO INPUT on two RCA connectors with
a corresponding balanced stereo LINE AUDIO OUT on a 5-pole terminal block
In particular, the WP-230 has:
 Trimmer controls for XGA EQ.
1
, and CV Level / EQ.
1
 Separate trimmer controls for right and left line audio level, and C and Y
levels
 Resolution exceeding UXGA, that ensures transparent operation
 A standard 12 Volt DC feed
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application. It is
recommended that in applications with high interference, shielded twisted pair
(STP) cable is used. However, the shield itself does create a capacitance that
degrades the frequency response of the machines. For shorter distances, of 50m
or so, shielded twisted pair (STP) cable is preferred because it provides protection
from interference (degradation is non apparent). For a long range application,
unshielded twisted pair (UTP) cable is preferred. However, the unshielded twisted
pair (UTP) cable should be installed far away from electric cables, motors and so
on, which are prone to create electrical interference.
Some Kramer twisted pair products include the Power Connect feature
2
. The
WP-230 does not have this feature.
1 Cable equalization
2 The Power Connect feature lets you power a transmitter / receiver system by connecting just one power adapter to either the
transmitter or the receiver. The other unit is fed over the same cable. The Power Connect feature applies as long as the cable
is heavy gauge cable (that is, it can carry power). The distance does not exceed 50 meters on standard CAT5 cable. For a
distance of 100 meters, separate power supplies must be connected to the transmitter and to the receiver simultaneously,
unless using heavy gauge cable

3.3 Recommendations for Achieving the Best Performance
Achieving the best performance means:
 Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables)
 Avoiding interference from neighboring electrical appliances
 Positioning your WP-230 away from moisture, excessive sunlight and dust

5.1 Installing the WP-230
To install your WP-230:
1. Connect the 5 RGBHV BNC output connectors
1
to the pre-installed
wiring in the wall box opening that connects to the XGA acceptor (for
example, a projector), as Figure 5 defines.
Figure 5: WP-230 RGBHV Outputs
2. Connect the LINE AUDIO OUT and / or the PC AUDIO OUT terminal
blocks, as one of the following:
Figure 6: Connecting the LINE AUDIO OUT / PC AUDIO OUT
3. Connect the wires of the coax cable to the CV OUT pins
2
, taking care that
polarity is correct.
4. Connect the wires of the coax cable to the Y/C OUT pins
3
, taking care
that polarity is correct.
5. Connect your 12V DC power supply to the POWER pins
4
, taking care that
polarity is correct.
6. Insert the WP-230 directly into the wall box opening, and then mount the
front panel securely using the screws.
1 The WP-230 could be used for component HDTV by connecting YPbPr in place of GBR, and not connecting H and V
2 Connect the composite video wire to the CV OUT pin and the Ground wire to the GND pin (see Figure 8)
3 Connect the luminance signal “Y” wire to the Y pin and the Ground wire to its corresponding GND pin, and connect the
chrominance signal “C” wire to the C pin and the Ground wire to its corresponding GND pin (see Figure 8)
4 Connect the wire labeled “+” to the +12V pin, and the wire labeled “–” to the GND pin
